Hearing Aid batteries have to be small, light and provide a steady level of power for hearing enhancement equipment to work well. A key feature of this battery application
has helped in the design of current Hearing Aid batteries: Hearing Aid batteries are
not used intermittently, but are typically used in one continuous stretch from unpacking
until their charge is fully used.
This unique usage profile enables the use of Zinc Air technology in Hearing Aid batteries. Before use, a small tab is removed from the battery. This allows air to enter the previously sealed battery, starting a chemical process that creates electricity. Unlike other batteries, the end of life of Zinc Air batteries is not determined just by use, but by the time by which this process comes to an end due to depletion of chemicals in the battery. The use of Zinc Air technology thus allows for smaller and lighter batteries that literally generate power while they are being used.
